Definitions

  • the present disclosure generally relate to a corrective sock assembly, and more specifically to a restrictive strap.
  • deformities of the toe frequently result from muscle imbalance aggravated by wearing poorly-fit shoes. Such shoes, having excessively high heels or being too short or narrow for the foot, may force the toe into a bent position,. Having the toes bent for long periods of time can cause the muscles to shorten, resulting in one of the deformity types mentioned above. This condition is often found in conjunction with bunions, calluses or other foot problems. Toe deformities can also be caused by muscle, nerve, or joint damage, resulting from conditions such as osteoarthritis, rheumatoid arthritis, stroke, Charcot-Marie-Tooth disease or diabetes. In certain age groups, the claw toe is present in every other woman. It can also be found in Friedrich's ataxia and several other neuropathies.
  • the main problem characterizing these conditions is usually the insufficient length of soft tissues, which constricts the toe, bends the joint, and forms a deformity (commonly a Z-deformity) of the ray.
  • PIPJ Proximal Interphalangeal Joint
  • MPJ Metaltarsophalangeal Joint
  • proximal phalanx the proximal phalanx
  • distal metatarsal bone the middle or distal phalanx.
  • Hallux Rigidus also referred to as Hallux Limitus
  • Hallux Limitus may develop in the big toe, bringing about pain during the push-off phase of walking, discomfort and increased pressure when wearing footwear.
  • One method is padding. Different types of shoe orthotics and socks may be used to pad and cover the prominent bones, thus relieving the pressure and reducing the pain, the discomfort and further damage.
  • Another method is based on lengthening of the soft tissues, which is achieved by physiotherapy on early stages, or surgically on late and severe stages.
  • a further method is based on surgical shortening of bones (osteotomy, joint excision, Du Vries procedure etc.).
  • Insoles are built to function as cushions which relieve the pressure under the metatarsals (metatarsal pad or metatarsal bar).
  • Insoles are usually made of a semi-rigid, non-washable material, while a much less common version is a rigid, washable insole.
  • the rigid ones are said to be less comfortable, and are often made of materials ranging from aluminum to plastics.
  • the foot moves relatively to the insole, and, therefore the insole has to be custom-made, for example by casting the foot in alabaster or low-temperature thermoplastic polymer.
  • the elevated areas have to include a relatively large surface area to adapt to the foot's motion.
  • orthotics include separate toe compartments, thus acting like a toe splint, but not to the entire ray. These orthotics do not usually have therapeutic padding under the metatarsal heads, the ray length is not adjustable, and there is a hygiene problem due to sweating of the feet. In specific orthotics which have the upper part of the toe covered by a polymer part, there is risk of callus formation; in the uncovered version, there are no restraints limiting toe bending.
  • Hallux Rigidus is usually treated with rigid or semi-rigid insoles, that prevent flexion of MPJ ("Morton's extension"), as well as with high shoes containing an anterior rocker.
  • MPJ MPJ
  • Another currently accepted method of treating Hallux Rigidus is surgical procedures such as MP1 fusion, MP1 implants and/or Cheilectomy. These procedures are usually expensive, painful and require a post-operative rehabilitation period.
  • U.S. Patent No. 4,263,902 to Dieterich discloses an orthopedic sandal for correction of hammer-toes and X-toe (Halux Valgus) being a dual lever arm arrangement pivotable on a horizontal axis transverse to the sole.
  • a pressure element for pressing the toes downward is on one arm and the other arm is fastened to the rearward portion of the foot so that as the food is lifted, the pressure element is pressed downwardly on the hammer-toes.
  • U.S. Patent No. 6,093,163 to Chong discloses a unitary device for the correction of hallux valgus, which is made of an elastomeric fabric material that includes a large portion that encloses the forefoot circumferentially, and a smaller portion that encloses the great toe circumferentially.
  • the fabric for constructing the device is cut in such a way that there is a bias towards varus of the great toe. Once the device is applied on the great toe and forefoot, the bias of the cut exerts a varus force on the great toe, thus correcting the valgus deformity.
  • U.S. Patent No. 5,772,621 to Unruh which is considered to represent the closest prior art, discloses a turf toe brace that includes a flexible boot adapted for anchoring the brace to a foot of a user, an elongate generally non stretchable strap releasably joinable to the boot by a fastening mechanism and a toe loop.
  • One exemplary embodiment of the disclosed subject matter is a sock assembly for correcting a deformed toe of a foot of a person, comprising a sock wearable on an at least a part of the foot, a strap connected to the sock and wearable on an at least a part of the foot and wrappable on an at least a part of the deformed toe as the sock it worn on the foot, consequently applying a corrective force on the deformed toe.
  • referring to aspects of a foot such as 'top', 'bottom', 'rear', 'front', 'posterior', etc. are with respect to a standing person.
  • a top view is from the head downwards.
  • 'proximal' and 'distal' refer, respectively, to 'close' to and 'away' from the heel.
  • referring to 'correcting' as with respect to a deformed toe or ray condition implies at least improving if not fully repairing the condition, and likewise, referring to 'corrective' or a variation thereof implies acting or employed for repairing the condition.
  • One technical problem dealt by the disclosed subject matter is correcting a deformation of a toe.
  • a sock assembly including a sock disposed on the foot or part thereof and comprising or connecting with a strap wrapped around a toe and/or a respective ray or part thereof, thereby applying a force on the toe or respective ray, yielding a non-invasive, repetitive and gradual correction of a toe deformation such as hammertoe, claw toe and/or a similar condition or conditions.
  • the sock as an assembly or combination of a sock with a strap enables to put the sock on the foot along with the strap whereby the strap is guided to a target toe or ray for applying a corrective force, and further provides for maintaining the position of the strap when the foot moves such as in walking, optionally further maintaining the position of other elements such as pads.
  • a potential technical effect of the disclosed subject matter is a self-positioning of a strap for correcting a deformation of a toe.
  • the corrective sock assembly includes a toe protector device, situated over the frontal part of the foot which is not covered by the sock, for protective and/or cosmetic purposes.
  • the corrective sock assembly introduces painless, or somewhat painful, force on the toe, wherein the force is optionally changeable such as by gradual adjustment of the strap length and/or elasticity.
  • the corrective sock assembly is designed for easy handling, as self-usage by the person, and may be used as an effective preventive measure, at least to a certain degree, for persons prone to toe deformity formation.
  • the entire corrective sock assembly is configured for easy and convenient wearing, and incorporation in a sock that covers part of or the entirety of the foot provides a sufficient or acceptable aesthetic appearance.
  • the corrective sock assembly is sufficiently thin to be worn inside footwear .
  • the corrective sock assembly includes one or more pads placeable beneath the foot's metatarsal head.
  • the corrective sock assembly includes one or more pads made of a shock absorbing material, such as silicone or a foamed polymer, and positioned under the heel and/or under the metatarsal base and/or under any other prominent part. Having a pad in the corrective sock assembly under the metatarsal base may, in some embodiments, replace tailor-made orthotics.
  • the pad or pads are adhered to the corrective sock assembly so that movement a pad in the corrective sock assembly is restricted.
  • a pad may be smaller compared to an insole-based padding since there is less freedom of motion of the foot in relation to the sock.
  • the corrective sock assembly may also be used before and/or after and/or instead of surgical treatment, especially in cases of SST (subluxation second toe).
  • the corrective sock assembly comprises a plurality of straps, and in some embodiments, a sock is not necessarily a full sock but, rather, a partial sock such as half-sock.
  • Fig. 1 schematically shows a corrective sock assembly 100 from a bottom view, according to exemplary embodiments of the disclosed subject matter, and a toe 114 lying along an axis 116 of an affected ray 130.
  • Fig. 2 schematically shows corrective sock assembly 100 from a side view
  • Fig. 3 schematically shows corrective sock assembly 100 from a rear view, according to exemplary embodiments of the disclosed subject matter.
  • Corrective sock assembly 100 includes a sock 102 and a restrictive strap 104 which is wrapped over the top part of toe 114, and under a proximal part of affected ray 130.
  • Restrictive strap 104 may be safely and comfortably anchored attached to an Achilles pad 110 made of a soft material and positioned over the heel bump (also "Tuber Calcanei") in a way that protects the tender Tendo Achilles enthesis area from direct contact with the strap.
  • Securing of restrictive strap 104 utilizes a reaction force generated upon movement of the foot, such as when walking or running, for exertion a straightening force on the toe, creating repetitive, gradual elongation of soft tissues of affected ray 130.
  • restrictive strap 104 may be crossed in an area following the wrapping of toe 114 under the metatarsal area, and opening again on two sides of the foot towards the Achilles tendon.
  • restrictive strap 104 is positioned, at least partly, inside sock 102, such that restrictive strap 104 is minimally or partially visible from outside of sock 102.
  • the frontal part of sock 102 includes suitable slits through which restrictive strap 104 is threaded in and out of sock 102.
  • Corrective sock assembly 100 may be placed anew every day on the foot, applying a tension such as to prevent pain or allow certain pain.
  • the tension is increased relative to previous positioning of corrective sock assembly 100, providing a gradual elongation of the soft tissues.
  • restrictive strap 104 is modular, enabling individual application to a plurality of rays or toes, optionally including all five rays or toes.
  • restrictive strap 104 comprises a plurality of straps, or, for example, restrictive strap 104 is splitted to sub-strips for individual rays or toes.
  • restrictive strap 104 comprises, or formed as, one or more bands that wraps or wrap a plurality of rays or toes, thereby applying corrective force simultaneously on a plurality of rays or toes.
  • restrictive strap 104 is attached to or connects to sock 102 over the heel and/or over affected ray 130, for example, by stitches, hooks, an adhesive, threaded through one or more apertures in the sock, or any other means such as hooks-and-loops.
  • a metatarsal pad 112 is placed at the bottom of sock 102 beneath the foot's metatarsal head or base.
  • restrictive strap 104 is treaded through metatarsal pad 112, or restrictive strap 104 is placed between sock 102 and metatarsal pad 112.
  • other manners are used for placing metatarsal pad 112 at suitable place, such as an adhesive.
  • metatarsal pad 112 comprises or made of a soft material, such as silicone or foamed material such as polystyrene foam.
  • metatarsal pad 112 creates a pivot that enables restrictive strap 104 to straighten affected ray 130 by mimicking or simulating or affecting a pull in the direction of intrinsic muscles' pull and utilizing the person's weight load as a source of corrective force. Since metatarsal pad 112 elevates one or more of the person's metatarsals, and restrictive strap 104 pulls down the affected toe, the intrinsic muscles are stretched and affected ray 130 deformation is straightened at least to some extent. Thus, metatarsal pad 112 complements and enhances the straightening force exerted by the restrictive strap.
  • a fastener represented without limiting as a buckle 108, is used to adjust the length of restrictive strap 104, and in some embodiments, a buckle pad 106 is attached to buckle 108 or at a respective position thereof on sock 102, providing comfort cushioning beneath buckle 108.
  • a toe pad 118 is placed over the IPJ (interphalangeal joint) of toe 114 and connected to restrictive strap 104 and to sock 102 using a bridge 120.
  • bridge 120 comprises or made of a wire, an elongated piece of fabric or other apparatus such as an elongated piece of plastic or metal.
  • toe pad 118 placed on or at least partly around toe 114 is configured to mitigate pain resulting from a shoe pressing on the toe, which is generally known with conditions such as hammertoe, claw toe, mallet toe and the like.
  • a separating pad such as toe pad 118 or a modified form thereof, is placed at least partly on a toe and/or two neighboring toes where the separating pad separates between the neighboring toes.
  • the separating pad detaches the toes from each other and/or provides cushioning to ease the discomfort and/or pain.
  • Fig. 5 and Fig. 6 shows corrective sock assembly 100 from a top and a bottom view, respectively, a according to exemplary embodiments of the disclosed subject matter.
  • a toe protector cup 122 covers the frontal part of corrective sock assembly 100, where, optionally, toe protector cup 122 have one or more cuts through which the restrictive strap 104 is optionally inserted.
